A typical adult human has a mass of about 70 kg. (a) What force does a full moon exert on such a human when it is directly overhead with its center 378,000 km away? (b) Compare this force with the force exerted on the human by the earth.

Step-by-Step Solution:

Solution to 7E Step 1 of 2 Introduction Consider two heavenly bodies A and B in the space and let the distance between them be ‘R’. According to Newton’s law of gravitation, the gravitational force of attraction between the two bodies is given by, Given, Distance between the person and full moon=378,000 km=3.78x10 m 8 Mass of the person =70kg 22 Mass of the moon =7.34x10 kg -11 3 -1 -2 G=6.67 × 10 m kg s
